Introducing GIS and spatial data

Geographical Information Systems

Geographical Information Systems are integral to modern systems of managing, analysing and reporting spatial data. The following introductory video sets out some of the basic GIS concepts.

At its core, a GIS is a management and display system for spatial data. There are many benefits of using such a system including:

  • effectively managing rapidly changing datasets
  • the creation of maps in a variety of dissemination formats
  • undertaking spatial analyses of varying complexity
  • reducing costs by re-using datasets

There is much talk about big data at present, and organisations are creating and/or downloading very large amounts of environmental and spatial data everyday. All of this requires collation, management and documenting so that new or dispersed users can come to the data and know how to use it. Spatial data come in many varied formats, such as satellite imagery, aerial photography, LiDAR point clouds and groundwater models. The effective management and use of data helps inform decisions.

Understanding your data will allow you to:

  • efficiently search your data holdings
  • share data internally and with clients in a standard way, cutting on processing costs
  • investigate the spatial or temporal relationships between your data
  • integrate your data across different software systems
  • creating efficient (semi-)automated processing work-flows
